My dog hardly barks, and never howls. However, my niece's fiance has a gorgeous little beagle named Sammy, and he howls and whines all the time (Sammy, not the fiance). I've only met Sammy a few times, but I've never heard him bark, and my niece told me he doesn't really, as even his barks turn into whines and howls. Sammy's cute as the dickens, and he's the smallest beagle I've ever seen.
